To provide a resin composition without causing powdering on its inflation molding and a molded film of the same.
This resin composition for the inflation molding is characterized by blending 99.95 to 90 pts.mass high density polyethylene having 0.938 g/cm3 density with 0.05 to 10 pts.mass ultra high molecular weight polyethylene. The ultra high molecular weight polyethylene is preferably the ultra high molecular weight polyethylene powder having 5 to 40 m mean particle diameter. Since the ultra high molecular weight polyethylene has 1,000,000 to 6,000,000 mass-average molecular weight, it does not melt in a usual inflation molding temperature region, and exhibits an effect of an anti-blocking agent. By using the ultra high molecular weight polyethylene powder excellent in abrasion resistance as an anti-blocking agent and co-extruding it by blending with the high density polyethylene, since the film surface becomes a rough surface to make a contact surface area with a stabilizing plate, etc., smaller, powdering does not occur.
